Q. Concentration of the $Ag^+$ ions in a saturated solution of $Ag_2C_2O_4$ is $2.2 \times 10^{-4}$ mol $L^{-1}$. Solubility product of $Ag_2C_2O_4$ is :
A) $2.42 \times 10^{-8}$
B) $2.66 \times 10^{-12}$
C) $4.5 \times 10^{-11}$
D) $5.3 \times 10^{-12}$
Explanation
[Solution] $[C_2O_4^{2-}] = 1.1 \times 10^{-4}$; $K_{sp} = (2.2 \times 10^{-4})^2 \times 1.1 \times 10^{-4} = 5.3 \times 10^{-12}$. Answer (4).
